It definitely wasn't a waste of time going through it. Confusing? A little bit.
I actually didn't know that parts of the cell are dead. Hmmm... Its a mystery
Its quite hard to define it (actually, there seem to be no real definition of it) and we can't fully understand it but it sure is worth living and of course getting the best out of it.
Yes, @audreybits, it's a mysterie, but a pleasant one :-) Life's a miracle and our most precious gift ,definitely worth living and enjoying as much as possible!
Yeah, it is! We shouldn't miss out on the opportunity of living it.
